Question

我遇到了与我的previous question相关的MySQL问题。

我最近需要从MySQL中删除一个表，现在需要在它的位置创建一个新表。我正在努力解决这个问题，因为正如MySQL Workbench所说，“该表已经存在。”由于MySQL Workbench的错误不是特别有用，所以我从错误日志中提取了一些内容。有什么问题？

我在Windows 8.1 Pro x64上运行MySQL 5.7。

Answer 1

由于表存在，只需使用drop table（http://dev.mysql.com/doc/refman/5.6/en/drop-table.html）

删除它

即。

drop table <table name>

由于桌子仍然存在，你一定做错了。

可以使用select

进行检查

即

select * from <table name>

Answer 2

看起来你的innodb表空间已经损坏了。

从percona查看此帖子

http://www.mysqlperformanceblog.com/2008/07/04/recovering-innodb-table-corruption/

这些工具

http://www.percona.com/software/percona-toolkit

他们会救你！

我不知道他们在Windows上运行的程度如何，但这些工具应该是一样的。

Answer 3

转到安装mysql文件夹的位置： C：\ APPS \ MySQL的-25年6月5日 - Win64的\数据\数据库名称

在databasename下，您将找到您的表名。手动删除此表并使用SQL Create Table命令再次创建它。

无法在MySQL中创建表，因为“它已经存在”
